Having thus descrlbed my invention what 1 6 3- 111 as new and desire tosecure by LettersPatent is:

i 1051f 1. In aprumng saw of the .class'described, a handle, a saw bladerigidly connected at one end to the handle, a'straining frame,

means on the inner end of the frame where.- by the same can be rotatablyattached to io the adjacent end of thehandle, means jas'sociated withthe outer ends of theframe and end of saidhead, a pair of laterallyeXtend ing spaced plates formed on the; outer end of said frame, theinnermost plate being dis posed at an incline, said plates havingopenmgs for receiv ng the circular head on the outer end of the blade,the circular plate on one end to the handle, a straining frame, a

V the outer face the outer end of the circular head engaging of theoutermostlaterally disposed plate. a

. 2. In a pruning saw of the class described, a handle, a saw bladerigidly connected at spaced collar and cap on the inner end of thestraining frame for loose engagement upon thesaw attached end of thehandle, whereb said frame is adapted forrotation f upon t einnerwend'portion ofvthe handle,

means at the opposite end vof the frame whereby the outer end of thesawblade may be attached thereto so as to permitthe frame to be rotatedaround the blade so as to position the same ativarious angleswithrespect to the cutting edge of the blade,'said means comprising acircular head carried on the outer end ofvthe saw'blade, a circularplate on the outer end of said head, a pair of spaced laterallyextending plates on the outer end of the frame, said plates being formedwith registering openings to receive the circular head, the opening intheinnermo'st plate being enlarged, the opening in the outermostlaterally extending plate, being slightly greater than the diameter ofthe circular head, the circular plate on the outer end of theheadengaging the outer face of the out-' ermost laterlly ext-endingplate, the innermost laterly extending plate being disposed on anincline. 1 r V In testimony whereof I aflix my signature,
